Inat'ormer application of mineIhave shown The invention comprises a bar 1, which is 6 a locking-bar comprising two members proprovided with one or more notches 2. The vided with registering post-receiving recesses mouth of the notch is preferably the wider 5 and slidable relatively to each other to effect part of the notch, and one wall of the notch a clamping of the posts. is cut back to form a shoulder 3. The wall The present invention is an improvement around the inner part of the notch is round over the former in that it is of much simpler to form a good fit for the post 4:. construction, of more compact form, that is 5 is a clamp pivoted to the bar, as at 6, and 2 thinner, lighter in weight, and may be manuprovided with a finger 50 for operating it and factured at slight expense compared to the with a toe 7, between which toe and the pivi'ormer bar. otal point is a notch 8. The toe 7 is curved The bar forming the present invention is eccentrically to the pivot 6, and when in its adapted to be clamped to the posts at any closed or operative position it projects for- 25 point and is adapted to be used between the ward beyond a line through the pivotal point covers to keep sheets which are on the posts 6 and the inner end of the notch 4 or the post in compact form, or it may be fastened to the when it is in the notch, said line extending loncover or to the inside of the back of the book gitudinally of the bar. or other covering for the loose leaves, or it By locating the pivot at one side of the inmay be attached to the outside of the cover. ner end of the notch and causing the toe to The uses of the bar are many, it being engage with the post upon the side opposite adapted for use in any book or loose-leaf recthereto and from the rear or bottom of the 0rd device where posts are used. notch the toe will continue to engage with the The securing of the bar to the posts is acpost even if the bar should be moved to the 3 5 complished very quickly,and the unlocking is rear and it would be drawn into tighter enaccomplished as readily. gagement therewith the more the bar were The accompanying drawings illustrate the drawn to the rear. In this manner the bar invention, and referring to the same, Figure will be prevented from being withdrawn I is a perspective view showing a part of a from the posts until after the clamps have 4 book open, the locking-bar being applied in been released, even though the parts should two places. Fig. II is a side elevation of a become worn, so as to permit more or less portion of the locking-bar. Two clamps are play between the post and the shoulder. At embraced in the part shown. The parts are the same time this construction of the clamps shown in section, and one clamp is raised and and notches permits of the bar being secured 45 the other closed in locking position. Fig. III to or released from the posts with but aslight is a perspective view of a loose-leaf binder, movement of the clamp, and when so secured showing another application of the lockingthe handle of the clamp lies substantially bar. Fig. 1V is an end elevation of the booklengthwise of the bar, so as to be as much out of the way as possible, which is a very important consideration, and especially when the device is used as a book.

The bar is applied to the posts, so that the posts lie in the notches 2, then the clamp is depressed and the toe 7 rubs against the side of the post and draws the bar tightly against the post, so the shoulder 3 lies in front of the post and faces the gripping edge of the clamp. The clamp is beveled to an edge 9, (see Fig. V,) so that when the clamp is set the edge 9 bites into the post, and thus the shoulder 3 and bite of the clamp holds the bar securely on the post.

By pivoting the clamp flatwise upon the bar, so as to be movable in a plane parallel with the side of the bar, the engagement of the sharp edge with the post is in a line with the length of the edge, which will preventits being dulled or broken when moved into or out of engagement with the post to such an extent as would be the case if it were pivoted, so as to swing toward and from the side of the bar.

As leaves are added to the posts the bar is adjusted upon the posts so that the clamp will bite a new part of the post, and slipping is thus positively prevented.

The bar may be removed from the posts by throwing up the clamps.

The number of notches in the bar and c amps therefor may be, as desired, dependent upon the number of posts; but it is obviously not necessary to employ a clamp for each and every post, although a notch must be provided for each post.

By employing a series of independentlyoperative clamps a very simple, cheap, and efficient locking device is provided. The leaves can be fastened together more tightly when clamps are provided, which operate independently of each other, because the operator may use one hand to presstogether the leaves at the point to be gripped while operating the clamp adjacent such point with the other hand.

In Fig. I the bar is shown as clamped to the posts intermediately to hold the sheets compactly pressed together. The bar is also in the same View shown as hinged to the back, the clamps engaging the posts near their ends.

Fig. IV shows a hinge 11, fasteningthebar to the back 12.

In Fig. III the bar is shown applied outside the cover of a binder and gripping the posts intermediately, and as sheets are added or removed the bar may be adjusted up or down to lie close against the cover.

What I claim is- 1. A locking-bar provided withshouldered notches, and means for contracting the space between the shoulder of each notch and apoint directly opposite said shoulder.

2. A locking-bar provided withshouldered notches, and means movable in a plane parallel with the side of the bar forcontraeting the space between the shoulder of each notch anda point directly opposite said shoulder.

3. A locking-bar provided with shouldered notches, and a clamp pivotally secured to the bar at one side of each notch and adjacent to its shoulder and provided with a portion movable in a plane parallel with the side of the bar into a position on the side of the notch diametrically opposite the shoulder and in advance of a line longitudinally of the bar and through said pivot and the inner end of the notch.

4. A locking-bar provided with shouldered notches, and a clamp pivotally secured to the bar at one side of the notch and adjacent to its shoulder and movable in a plane parallel with the side of the bar, the pivotal point of the clamp being on a line longitudinally of the bar and through the inner end of the notch said clam p being provided with an eccentric toe adapted to be moved into a position on. the side of the notch opposite the shoulder, whereby the space of the notch opposite said shoulder is contracted.

5. A locking-bar provided with shouldered notches, and aclamp pivotally secured flatwise to the bar adjacent to each shoulder and movable in a plane parallel with the side of the bar, the pivotal point of the clamp being on a line longitudinally of the bar and through the inner end of the notch said clamp being provided with an eccentric toe adapted to be moved into a position on the side of the notch opposite the shoulder, whereby the space of the notch opposite the shoulder is contracted, the inner edge of said toe being inclined to form a cutting edge.

6. The combination, with the back of a looseleaf holder, of a notched locking-bar pivot-ally secured thereto, and means on the bar at each notch for engaging with the posts of the holder and holding each of them behind its respective shoulder, thereby clamping the bar to the posts.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, in the county of Los Angeles and State of California, this 22d day of July, 1903.
